CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 512,541, dated Januarye, 1894.. Application filed September 9, 1892. Serial No. 445,428. (Nomodel.)

To all whom, it may concern:

Be itknown that I, WILLIAM C. DOUBLE- DAY, residing at Columbus, in thecounty of Franklin and State of Ohio, have invented certain new andusefullmprovements in Corn- Harvesters; and I do hereby declare thefollowing toy be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in corn harvesters,-its objectbeing to produce i a corn harvester which shall be of simpleconstruction, sure` in its operation and effectual in the performance ofits functions.

With these objects in View the invention consists in certain novelfeatures of construction and combinations and arrangements of parts ashereinafter set forth and pointed out in the claims.

In the accompanying drawings: Figure l is a plan View of a portion ofthe machine, parts being shown broken away and in section. 2 is a sideelevation. Fig. 3 is a front view. Fig. 4 is an elevation showing theshocking devices in position to receive the corn. Fig. 5 is a detailView of the shocking mechanism, showing the positions of the parts whenready to discharge a shock. Fig. 6 is an enlarged detail view of theshocking mechanisms showing the positions of the parts when in the actof discharging a shock. Fig. 7 is a detail View illustrating parts ofthe shocking mechanism. Fig. 8 is a detached plan view illustrating thefeed chains.

A represents a base or -frame, from the ends of which standards aproject upwardly, the upper ends of which are provided with suitablebearings for a roller b for the accommodation of an endless carrierhereinafter to be referred to. The standards a are braced by suitabletimbers, and in proximity to said standards a, shorter uprights orstandards a are located. Bars or timbers c connect the standards a attheir upper ends as shown in Fig. 2 and resting on said cross timber,and a similar one, not shown, connecting standards a, a. and projectinglaterally from the machine are lateral timbers d, which support theshocking mechanism as presently explained. A platform e is built at therear end of the machine, being secured to the rear uprights or standardsa, 0.',-this platform being intended for the accommodation of theoperator.

A beam or bar f extends vacross the front of the machine at a pointabove the base or frame A, and is secured to a diagonally disposedtimber f, which extends from the base A to` a point preferably slightlyTabove the standards a. At the side of the machine farthest removed fromthe standards o., a beam g is located and supported at a point abovetheframe or base A about in line with the bar or beamf, by means ofposts g-. From this arrangement of bars or beams it will be seen that aspace g2 will be left between the end of the b'ar f and the side of thebar or beam g. Below the bar or beamf a shoe or guide arm 71 projectsforwardly and laterally and below the bar or beam g a shoe or guide armh projects forwardly and laterally, said shoes or guide arms projectingforward from the base or frame A, and laterally in opposite directions.A post or shaft i projects upwardly and is secured at its upper end to abracket 112 extending from the bar or beam f and at the lower end to theshoe h in proximity to the end thereof. A similar post or shaft t" issecured at one end to the end of the bar or beam g and at the other endto the shoe h near its free end. The bracket ft2 is located at the endof the bar or beam f and extends parallel with bar or beam g. A shaft jis revolubly mounted in one end of said bracket and in the inner end ofthe shoe h, and carries two sprocket wheels j2. A similar shaft j* isrevolubly mounted at one end in the bar or beam g and at the other endin the rear end ofthe shoe h. This shaft also-carries sprocket wheelsj.A fixed post or shaft 7c is located between the forward end of thebracket t2 and the shoe h, and a similar fixed post 7o is locatedbetween the end of the bar or beam g and the shoe h. On the posts la, 7osprocket wheels Z are loosely mounted.

posts t' and rl in line with the sprocket wheelsZ. Passing over thesesprocket wheels are four (more or less) sprocket chains n having teethn,-said sprocket chains being adapted..` to feed the corn to an endlesscarrier B. The endless carrier B passes over a roller b mounted Sprocketwheels m are loosely mounted on the,

IOC

in the base A and over the roller l) at the upper ends of the standardsa. Sprocket wheels o, o are secured to the shafts of the rollers b, b'and are connected by a sprocket chain b2, whereby motion may be impartedfrom one of said rollers to the other. The shaft of the roller b isprovided with a bevel gear p, which meshes with a bevel gear p carriedby a shaft p2. The shaft p2 extends to the opposite side of the machinewhere it is provided with a pinion p3 which meshes with an internal gearp4 of the carrying wheel p5. The opposite carrying wheel p5 is carriedby a short axle p7 secured to the base A. From this constructionit willbe seen that when the machine moves forward the endless carrier will beelevated. The shaft p2 also has secured to it, bevel gears p8, p9, whichmesh, respectively, with bevel pinions q, q', carried by the revolnbleshafts 7, 7"1, whereby to impart motion to the feed chains n. Spanningthe space between the shoes h, 7L preferably at points in proximity tothe inner ends of the Haring portions thereof, is a finger bar r, onwhich a reciprocatory knife barr is located. A feed board r2 extendsfrom the cutting mechanism thus produced to the base or frame A wherebyto prevent the escape of grain. On the shaft j a gear wheel s is securedand adapted to mesh with a similar gear wheel s supported by the frameA. The gear wheel s meshes with a pinion s2 located near one end of theknife bar. One end of a pitman sais pivoted eccentrically to the pinions2 at one end and at the other end pivotally connected to the knife bar.In this manner motion will be imparted to the knife bar.

Mounted at its ends in the lateral timbers d is a shaft C, to which issecured in proximity to one end, a U-shaped bracket or holder D. Thisbracket or holder is intended to receive the butt end of the shock ofcorn and the ends of the stalks of corn comprising the shock will bemaintained even with each other by means of an end board or abutment D.In proximity to the opposite end of the shaft C, an arm E is looselymounted, the upper end of whicharm is adapted to receive the hollowshank t of a bracket or holder F, said shank being provided with anelongated slot t for the reception of a pin t2 projecting from the armE, whereby a limited oscillatory motion of the holder F will bepermitted. The lower end of the arm E is connected to one of thestandards a, by means of a chain 253 or other fiexible connection,whereby to limit the movements of the holder F in both directions. `Aclamping arm G is hinged to the bracket or holder F, a portion of saidarm being preferably curved as shown in Fig. 6, and the free end madestraight to produce a handle G. At the junction of the handle G and thecurved portion of the clamping arm, a perforation u is made, for thereception of the arm u of the holder F, whereby the clamping arm will bepermitted to close down upon and clamp the corn within the holder. A dogH is pivotally connected to the clamping arm G and adapted to engageteeth u2 made in the arm u of the holder F. A cord ug is attached to anarm u* of the dog and passed through suitable loops or eyes on theclamping arm,by means of which cord the dog may be released from theratchet teeth when it is desired to release a shock. Disks v, arepreferably secured to the shaft C at opposite sides of the arm E, andpassing through said disks, in front of the afm E, 1s a pin fu'. Ahandle I is secured to the shaft C, by means of which to operate saidshaft. A notched collar w is secured to the shaft C, and is adapted tobe engaged by a pawl or dog w', whereby to retain the holders D, F, inproper position to receive the corn. The holders and F and the partsattached thereto constitute my improved shocking apparatus.

At the base of the endless carrier or apron, guide a: is located, toprevent the escape of the corn. A similar guide no is located at the topof the carrier to properly guide the heads of the stalks to the holderF.

A suitable tongue J for the accommodation of the draft animals will beprovided as shown in Fig. 3.

During the operation of the machine, the corn will enter between thefeeding chains, and be fed thereby to the cutting devices and thence thecorn will fall backward upon the endless carrier, the portion upon thebelt being of sufficient Weight to counterbalance the butt ends so thatnone of the stalks will drop in lthe space between platform r2 and theelevator. When these devices are in position to receive the corn theywill assume the position shown in Fig. 3, and be retained in thatposition by means of the `dog or pawl 'w'. When a sufficient quantity ofgrain has entered the holders D, F, it will be tied and the clamping armG will be brought down upon it and made to clamp the shock in proximityto its head, the dog H retaining it in its clamped position byengagement with the ratchet teeth u2. It may be here stated that the dogw only retains the holder D in its upright position and prevents theturning of the shaft C. The arm E bearing against the pin o prevents theoutward movement of the holder F when the shaft C is locked, and thechain t3 prevents inward movement thereof. The shocking devices beingnow filled and clamped, the dog w will be raised to release the shaft C,andthe handle I operated to turn the holders to discharge the grain. Theholder D will be inverted to release the butt of the shock. In themeantime the holder F has made but one-fourth of a revolution, beingprevented from further movement by the chain t3 and the pin e. When thebutt of the shock shall have been released as above set forth, the headbeing clamped in the holder F, will cause the holder F to turn andassume a horizontal position as shown in Fig. 6, and thus hold the shocksuspended. The cord as will now be pulled to release the dog IOC IZO

H, whereupon the clamping arm will iiy back and release the shock, whichwill be thus discharged and made to stand upon the ground. The weight ofthe clamping arm when the holder is open will now cause the holder F toassume its position parallel with the holder D. The handle I will now beagain grasped and the parts brought back to their normal positions readyto receive another supply of corn.

In order to provide means for throwing the operating mechanism into andout of gear, a clutch y will be provided on the shaft p2 and adapted tothrow the pinion p3 into and out of gear. A lever y is provided foroperating said clutch and cords y2 are connected to said lever foroperating it.

Slight changes might be made in the details of construction of myinvention without departing from the spirit thereof or limiting itsscope. I-Ience Ido not wish to limit myself to the precise details ofconstruction herein set forth, but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
